As shown, the instrument case A, is formed with apertures A20 for the passage of conducting leads connected to the' ins'trumentalities normally housed in thecasing, but their use is not a characteristic of the present invention.

As will be understood by those skilled in the art, l

the'form of instrument mounting employed in any particular installation ordinarily depends upon conditions at that installation. Considerment casing forms for use inv mounting the same instrument-indifferent ways. The provision of a casing adapted for interchangeable use with the results in lower costs. The casing constrution illustrated not only facilitates the use of whichhinge lugs it which are required for use 1n mounting the instrument in any of the above described ways.

While in accordance with the provisions of the statutes, I have illustrated and described the best my invention now known form of embodiment of to me, it will be apparent to those skilled in the invention what I vsecure by Letters described my and desire to Having lnow claim as new Patent, is:
